Railway wagon lower side door self-locking type locking device and inwards-concave lower side door comprising locking device
The invention discloses a self-locking type locking device for a lower side door of a railway wagon and a concave lower side door comprising the locking device. The locking device comprises a lock seat, a lock iron and a lock rod, the lock seat comprises a mounting plate and two vertical plates, lock rod holes are formed in the upper parts of the two vertical plates, and limiting grooves are formed in the lower parts of the two vertical plates; the lock iron comprises a lock iron body, a pressing rod is arranged on the upper portion of the lock iron body, and the pressing rod can be embedded into the limiting groove to form a first hinge point. Two lock rod mounting cylinders are arranged at the lower part of the lock iron body; the lock rod comprises a rotating rod, the two ends of the rotating rod are connected with arc-shaped elastic rods respectively, lock rod rotating shafts are arranged at the upper ends of the arc-shaped elastic rods, the rotating rod is installed in the lock rod installation cylinder and rotationally connected with the lock rod installation cylinder to form a second hinge point, and the lock rod rotating shafts are installed in the lock rod holes in the same side and rotationally connected with the lock rod installation cylinder to form a third hinge point. The locking reliability of the lower side door of the railway wagon can be improved, and the problem that an existing hasp locking device is difficult to close after hasp iron is overturned and the lower side door is deformed is solved.
本发明公开了一种铁路货车下侧门自锁式锁闭装置及含该锁闭装置的内凹式下侧门，该锁闭装置包括锁座、锁铁以及锁杆；锁座包括安装板和两个立板，两个立板的上部设置有锁杆孔，两个立板的下部设置有限位槽；锁铁包括锁铁本体，锁铁本体的上部设置有压杆，压杆可嵌入限位槽内形成第一铰接点；锁铁本体的下部设置有两个锁杆安装筒；锁杆包括转动杆，转动杆的两端分别连接有弧形弹性杆，弧形弹性杆的上端设置有锁杆转动轴，转动杆安装在锁杆安装筒内与其转动连接形成第二铰接点，锁杆转动轴安装在位于同一侧的锁杆孔内与其转动连接形成第三铰接点。本发明可提高铁路货车下侧门的锁闭可靠性，解决既有搭扣锁闭装置扣铁翻转和下侧门变形后难关闭问题。
